PHP Oracle Database Extension : OCI8 is the most available
and scalable PHP adapter for the Oracle database. It is included with PHP, and is also separately downloadable for upgrading older PHP
releases. OCI8 works with PHP 4 and PHP 5, and will compile with Oracle 9iR2, 10g and 11g client libraries. Oracle's standard
cross-version compatibility and connectivity is applicable, so OCI8 can connect to older or newer databases, locally or
remotely. The latest OCI8 release includes support for Oracle Database 11g Database Resident Connection Pooling (DRCP), and for Fast
Application Notification (FAN) [whitepaper
here], and also has support for Oracle's authentication and end-to-end tracing meta data attributes [article here]. These
features improve scalability and availabilty of the OCI8 extension.

Database : MySQL -- The world's most popular open source
database. MySQL Community Edition is the freely downloadable version. Commercial customers have the flexibility of choosing from multiple editions to
meet specific business and technical requirements. Also available for free is the MySQL Workbench for SQL Authoring, System Administration, and schema
modeling.

Database : Oracle
Berkeley DB 11g -- provides the complex data management features found in
enterprise class databases. These facilities include high throughput, low-latency reads, non-blocking writes, high concurrency, data
scalability, in-memory caching, ACID transactions, automatic and catastrophic recovery when the application, system or hardware fails,
high availability and replication in an application configurable package. Simply configure the library and use the particular features
available to satisfy your particular application needs. Berkeley DB can be configured to address any application need from the hand-held
device to the datacenter, from a local storage solution to a world-wide distributed one, from kilobytes to petabytes.

Virtualize : Oracle VM
VirtualBox -- powerful Cross-platform Virtualization Software for x86-based systems. "Cross-platform"
means that it installs on Windows, Linux, Mac OS X and Solaris x86 computers. And "Virtualization Software" means that you can create
and run multiple Virtual Machines, running different operating systems, on the same computer at the same time. For example, you can
run Windows and Linux on your Mac, run Linux and Solaris on your Windows PC, or run Windows on your Linux systems.

Oracle VM VirtualBox is available as Open Source or pre-built Binaries for Windows, Linux, Mac OS X and
Solaris.

OTN hosts some pre-built Developer VMs , including an Oracle Tuxedo Web Application Server VM showing PHP support. There is also a Zend Server VM for PHP created by Zend. Zend Server is a complete,
Oracle-enabled, enterprise-ready Web Application Server for running and managing PHP applications that require a high level of reliability,
performance and security. Zend Server is available in community and supported editions.

Operating system : Oracle Linux -- free to download and distribute. As one of the most widely deployed operating systems today, Linux is increasingly being
adopted for cloud-based solutions. Oracle Linux is the most complete and integrated solution available and delivers higher performance and better
reliability at up to 7 times lower cost than Red Hat. Why Choose Oracle
Linux over Red Hat Linux?

Oracle Linux 5.6 and 6 introduced PHP 5.3 packages. Subscribers to the Unbreakable Linux Network have access to an additional
pre-built PHP OCI8 RPM, and also direct access to an RPM for installing Zend Server .

Client Libraries : Oracle Instant
Client -- a small footprint set of libraries that allows applications and tools to connect to an existing Oracle
Database. Oracle OCI, OCCI, Pro*C, ODBC, and JDBC applications work without modification.

The PHP OCI8 extension can be built with Oracle Instant Client to connect to a remote database.

Instant Client is provided under a separate OTN Development and Distribution License for Instant Client that
allows most licensees to download, redistribute, and deploy in production environments, without charge.
